anticoagulation determination for AFIB
CHA2DS2VAS
CHF---1 HTN----1 age >75---1 DM--1 Stroke, TIA, TE-----2 Vascular disease (prior MI, PAD, CABG)---1 Age 65-74----1 Sex---female---1
Score 0= no anticoag
score 1— no coag or just ASA (81-324) or OAC
score 2—- OAC
score >3—- OAC
rhythm control for AFIB
- under 48 hours
- over 48 hours
- unstable
CCB (diltiazem or verapamil)
or
BB like metoprolol
under 48 hrs: cardioversion, amiodarone (obtain transesophageal echo (TEE) to determine if a clot is present prior to cardioversion)
over 48: anticoagulate for 21 days prior to cardioversion
unstable= synch cardiov
list DOACs
direct oral anticoags
dabigatran, rivaroxaban, apixaban, or edoxaban
-ban or -an
**better than warfarin
when to give warfarin for afib
mechanical heart valves, mitral stenosis, unacceptable increase in cost, EGFR < 30 ml/min, on certain medications (phenytoin or certain antiretroviral therapy
Adjusted-dose warfarin target INR is
2.5
range=2-3
what is top picked DOACs
apixaban or Eliquis best balance of safety and efficacy,
Xarelto (rivaroxaban) for once-daily dosing
dont jump to what meds for AFIB anticoag control
ANTI PLATS
- asa
- clopidogrel
These antiplatelets aren’t as effective as an anticoagulant in reducing stroke risk in atrial fib patients…and bleeding risk may not be lower
consider what drug if CrCl is below 30 mL/min
warfarin
what is clopidogrel
antiplatelet
when would you have to lower the dose of ELiquis
if taken with Clarithromycin
Virchow triad
Stasis, hypercoaguability and trauma (like surgery)
Describe homan’s sign
Extend the leg…and then push the foot towards the head (Doris flex) and will cause pain
DVT
- diagnosis —-GS, 1st line, others
- tx
DX= 1st line is venous duplex US, D-diner (will r/o DVT in low risk PT), GOLD STANDARD= venography,
TX
- Immediate anti coagulation:
* LMW heparin + warfarin, LMWH + either Dabigatran or Eboxaban as mono therapy with Rivaroxaban or Apixaban (all DOACs) or fondaparinux, or the oral factor Xa inhibitors - IVC filter—- 3 indications
* recurrent despite adequate anticoagulation
* stable PT in whom anticoagulation is contradinicated
* right ventricular dysfunction with an enlarged RV on echo - Thrombosis is or thrombectomy: generally not done—reserved for massive DVT or severe cases
Tx for a pregnant woman with DVT
LMWH as initial and long term tx
Leg pain that worsens with walking, elevation of leg
Peripheral ARTERY disease
Leg pain that is improved with walking or elevation
PVD
Cyanotic leg with dependency
PVD
Red leg with dependency
PAD
Leg ulcers at the medial malleolus with uneven ulcer margins
PVD
Leg ulcers at lateral malleous with clean margins
PAD
Leg/foot has brownish pigmentation—— eczema toys rash, thickening of skin
PVD
Atrophic changes to leg/foot…. thin shiny skin, loss of hair, muscle atrophy, pallor, thick nails, Mottled appearance
PAD
Pericarditis
- two MCC
- CM-what makes pain better/worse
- DX
- TX *****
MCC=viral (coxsachkike virus , echovirus) and idiopathic
OTHER CAUSES= dressier syndrome (post MI + fever +pleural eff), autoimmune, uremia, bacterial, radiation, medications
CM
*sudden onset CP==sharp, worse with inspiration, persistent, postural—-worse when supine and improved with sitting forward
DX
- EKG: diffuse ST elevations in precordial leads (v1-v6) with PR depressions
- +/- cardiac enzymes
- ECHO:
TX
- NSAIDs or ASA first line x7-14 days
- Colchicine 2nd line
If dressier syndrome—> ASA or colchicine (AVOID NSAIDs bc they can interfere with Myocardial scar formation)
Sinus rate that varies with inspiration
Sinus arrhythmia
systolic-ejection murmur (SEM) heard in the second intercostal space (ICS) at the right sternal border with radiation to the carotids and the apex.
